In an effort to help solve the world’s energy crisis, GravityLight has created a useful marvel in these modern times.
It’s incredibly simplistic as far as user-friendly operation is concerned. And, each cycle provides 20 minutes of light.

So, here’s how it works.
According to the official website, in order to power this light, it requires a weight (included).
The source notes that the weight needs to be about 27 pounds or 12 kilograms. Not to worry.
GravityLight mentions that since the weight is on a pulley system, it only feels like 6 pounds or so.
The weight fits into the bag which is included with the kit.
“As the weight falls it turns a gear train, driving the motor that powers the LEDs…This movement powers a drive sprocket, which rotates very slowly with high torque (turning force). A polymer gear train running through the product turns this input into a high-speed, low-torque output that drives a DC generator at 1600 rotations per minute.”

The source mentions that GravityLight needs to be hung high enough that there’s a 6-foot drop space beneath.
That’s how far the weight and bag need to travel within the 20 minutes of provided light.
Check out the following video to see a few of its applications.
All in all, let us know what you think about this particular innovative invention.
